From 88bab55da9ecb7c77f35110a623f2c1dcd80b774 Mon Sep 17 00:00:00 2001
From: Josip Pavic <Josip.Pavic@amd.com>
Date: Fri, 23 Aug 2019 20:54:12 -0400
Subject: [PATCH 3826/4256] drm/amd/display: define parameters for abm 2.3
[Why]
Current configuration 0 is just a placeholder, and final parameters needed.
Also, configuration 1 is expected to emulate ABM 2.1 but is too aggressive.
[How]
Redefine configuration 0 with the finalized parameters, and increase the
contrast gain of configuration 1 so that it properly emulates ABM 2.1.
